Lost a story here

There is a story on her that I read once, but I forgot to track it. Maybe someone could point it out to me?

It's aTwilight/Trixi story.

Twilight is asked to go to Manehattan to help "someone in dire need of friendship" and on the way there, her train is attacked. She finds out too late that the someone in need is Trixie, they have an epic battle in her yard.

Later on they get crazy drunk and in a bar fight.

And later than that Twilight is captured and tortured, believed to be a terrorist, before Celestia herself and royal guard arrive to bust her out.

Anyone have any idea?
